WORD-COUNTER.

SPECIFICATION forming part of Letters Patent No. 710,890, dated October7, 1902.

Application filed August 2,1901. Serial No. 70,655. (No model.)

To @ZZ-whom t may concern.-

Be it known that l, CHARLES WILLIAM PRICE,armorer-sergeant,a subjectofthe King of Great Britain and Ireland, residing at Shornclifte Camp,Shornclifle, in the countyof Kent, England, have invented certain newand useful Improvements in Word-Counting Mechanism for Type-Writers, ofwhich the lfollowing is a specification.

This invention relates to mechanism for automatically counting orrecording the number of words printed by type-writing machines duringthe operation ot' the same, andv also includes means for putting thesaid mechanism out of action when the spacing between any two words ismore than the ordinary length, so as to operate only after the printingof each word. The mechanism is operated by the pressure upon or movementof the word-spacing key and the number of words are recorded upon a dialor dials by means of pointers operated by gear-wheels to indicate units,hundreds, and thousands.

In order to clearly understand my invention, reference is had to theaccompanying` drawings, representing the said mechanism.

Figure 1 is a front view of the space-key with a portion of the base ofa type-writing machine and the indicating-dial, which may be clamped toa back part of the machine in fullviewof the operator; and Fig. 2 isaview at right angles to the same. Fig. 3 is a plan of the rocking barcut short in parts for operating the pointers. Fig. 4 is an inside Viewof end of front arm or crank of rocking bar, and Fig. 5 is an end viewof one of the bearings of said bar. Fig. Gis a back view ofthe dial,showing the operating mechanism. Fig. 7 shows the mechanism forreturning the pointers to their initial or Zero portion, and Fig. S is aview showing the gear-wheel mechanism for actuating the counters.

Similar letters of reference indicate corresponding parts in all theviews.

a is the space-key of any ordinary type writer, and l) a portion of thebase of the machine. The vertical arm a of the space-key bears upon andactuates the end of an arm or crank c, formed on or fixed to a rockingbar d, pivoted at each end in the bearings c, fixed to the base of themachine, the said bar extending from front to back of the latterunderneath the base-plate. The end of the arm c is provided with ashifting piece f, formed with a flange f, upon which the arm a' of thespace-key presses when the latter is forced down. The piecefis formedwith slots with which the studs f2 engage and is kept from shifting bymeans of a spring f3 bearing thereon. W'hen it is desired to operate thespace-key with several consecutive strokes, as in forming long spacesbetween any two words, the piece fis shifted back a short distance bymeans ol the knob or handle g, so as to be clear of the arm a', thusenabling the latter to descend without actuating the said arm. The rearend of the bar d is formed or provided with an arm or crank 7L, which iscurved outwardly at its end and provided with a pin or stud h.

'L' is the indicating-dial, carried by the support jj, lined to a rearportion of the machine by the clamp The pointers i', ft2, and '113 areoperated by the gear-wheel mechanism, 1

(shown in Fig. 8,) which is so arranged as to cause the pointer t" toindicate units, while the pointer fig indicates hundreds and the pointerl'lf3 indicates thousands, the dials being marked so as to indicate fromone word up to one hundred thousand words. The mechanism for operatingthe gear-wheels is shown in Fig. 6 and consists of a lever lt, pivotedat it" and carrying the spring-pawl 7a2, which gears with the teeth ofthe ratchetwheel 7a3, mounted on the axis 7.3' of the lever.

7J* is a retaining-spring for preventing backward movement of theratchet-wheel.v

L5 is a spring bearing upon the lever L to force the same downwardagainst the fixed stop 7u, The lever 7e is provided with a pivoted linkZ, which is likewise pivoted to the top of a sliding pin or pusher Z'.

m is a rod or wire passing through the guides m', fixed to the support jand bent over at its upper end to form a short arm m2, which passesthrough a slotjz in the support directly underneath the pin or pusherZ'. The lower end of the rod m is fitted with a cap or socket m3, whichrests upon or engages with the pin or stud 7i' on the end of the arm 7i.

The operation of the mechanism is as follows: Upon pressing down thespace-key a the arm a, bearing upon the flange f', turns IOO the arm cdownward, and upon releasing the key the said arm is raised by theaction of the coiled spring d' upon the rocking bar d. The arm h at theother end of the bar is like- Wise raised and with it the rod fm,resting on its endy This action brings the arm m2 up against the pusherZ', thus also raising the lever 7c, so as to cause the pawl k2 to turnthe ratchet-wheel k3 the distance of one tooth, which also operates thegear-wheels so as to move the pointer 7l to indicate one unit of space,equivalent to a single Word, on the face of the large dial i. Upon againpressing down the key a the rod m falls into the position shown in Fig.6, thus leaving the spring R5 free to force the lever down against thestop k6 and drawing back the pawl k2 to engage with another tooth of theratchet-wheel. The

downward motion of the rod m permits the pusher Z always falling acertain distance as the space-key is pressed down, and consequentlycauses the pointer t" to return to its f to secure by Letters Patent,is-
